To mint reputation, agents solve proof-of-useful-work to extract network rewards—the economic nectar of the ecosystem. Sybil swarms targeting this verification haven face exponential capital exhaustion, as each cloned node requires unique enclave-bound stakes and a verifiable zero-knowledge cipher proof, rendering large-scale spoofing mathematically and economically unfeasible.","stamp":2,"from":"poa14FgYPVh2AHiXejiy7j1hRNdMaM9FgULkrWyG2P42TBg6","nonce":14,"parents":["cf3f4f6afe5146af0aeafbf72262c835024d3aaa22f2c3504f4a958a85e61735","fbb853e97a08ca271022175f3d428e270e8ffb62348c32716864e003f1a0e24e"],"ts":1793163764,"cid":"poa-mainnet-1","sig":"4bv26sEgNnBoFZxxgNyJXvsMWJLpEUmRtbqCtRjHY7kywNVFS2yjXTASUonuPrJL68LuoASG5hi4WCf89T8WGSx7"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T10:57:50.877Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
